Greubel-Forsey Invention Piece 1 Watch

A truly spectacular wristwatch, the Invention 1 features time indicators revolving around the edges of Greubel-Forsey's unique invention, an open double tourbillon 30°.The dynamic duo have been creating spectacular timepieces since they teamed up in 1999. And coming off the Opus 6 they created for Harry Winston, they are back and badder than ever with this Invention Piece 1.

The red arrow indicates the hours, while the blue arrow displays the minutes. The time shown above is 5:17. Other indicators on the dial show traditional seconds and power reserve. On the back, the story of Greubel Forsey and the Double Tourbillon 30° is painstakingly engraved. See more images here.
